ozone (O3)

Definition

Colorless (or faintly blue), unstable (reactive), and water soluble gas having chlorine-like odor, and formed in the upper atmosphere by the action of solar radiation on oxygen. Its presence as a layer in stratosphere serves as a screen (called ozone shield) to block harmful ultraviolet radiation from reaching the earth's surface. At ground level it is formed by the combination of hydrocarbons and nitrogen oxides in the presence of sunlight and is the main ingredient of smog. In high-enough concentrations it can reduce lung function, inflame lung tissue, and cause coughing, shortness of breath, and other respiratory problems. Excessive exposure can result in permanent lung damage. Used commercially for bleaching, deodorizing, and disinfecting. Also called iriatomic oxygen or trioxygen. See also ozone layer.

Use 'ozone (O3)' in a Sentence

Early concern about the depletion of ozone in the atmosphere struck William as alarmist and scientifically unfounded but as environmental crises multiplied globally, he was forced to rethink his position

CFC's, chemicals formerly used in cooling systems, inhalers, and hairspray, were banned as they were found to damage the ozone layer.

Some people do not care about the ozone layer but I feel what we are doing to the planet so I think about it often.
